Abstract

A method of coating an active material is provided. The method comprises contacting an active material with a film-forming composition comprising an aqueous dispersion of an amylose-alcohol complex, an insoluble film-forming polymer and a plasticiser at a temperature of less than 60° C. The method finds particular application in the preparation of dosage forms comprising active materials that are unstable at temperatures in excess of 60° C. The compositions prepared in accordance with the method can be used to deliver an active material to the colon.
